| Building Control 
Option Card Slots
Three card slots in the BCU provide the flexibility to
configure an RS-232 communication card or modem, an ARCNET communication card, and/or an
ARCNET communication hub card.
Assignable Inputs
Each BCU can accommodate two universal inputs. Use UCMs to
gain additional inputs.
Modular Installation
The BCU can be installed in a series of steps to increase
efficiency and ease of installation, and to protect the hardware.
Enclosure Specifications
The BCU panel has a NEMA Type 1 rated enclosure designed
for indoor installation only. The BCU is designed to operate between 32° F to 120° F
(0° C to 49° C) at relative humidities between 10% to 90%, non-condensing.
Tracer 100 Series Systems: Tracer
L, 100, and 100i
The Tracer 100 series panels are capable of monitoring HVAC
equipment, providing the operator with management information, and communicating with
other Tracer series systems. They also provide building automation and energy management
functions through standalone control of HVAC equipment.
ICS Capability
Tracer L, 100, and 100i communicate over a twisted wire
pair with UCMS on Trane HVAC equipment or Trane general purpose controllers on non-Trane
or existing equipment. The ICS approach provides extensive monitoring and control
capabilities while simplifying and reducing the cost of installation.
Software Capabilities
Tracer L, 100, and 100i provide the following features and
capabilities to monitor equipment:
- Zone control groups associated HVAC equipment
into zones to coordinate their operation. Zone parameters include occupied/unoccupied
heating and cooling setpoints and temperature offsets for demand limiting and duty
cycle modes.
- Reports and logs provide the operator with access to
important system data. The following types of reports are available:
- Current, daily, and monthly energy use
- Yearly degree days
- Weekly temperature
- Event logs
- Input/output status
- Integrated Comfort system equipment status
- Monthly totalizing
- Monthly and yearly demand limiting
- Weekly and monthly timed override
- Custom status
- Run time and maintenance software monitors equipment
run time, equipment starts, and calendar dates to generate maintenance messages.
- Custom messages can be created and used with run time
and maintenance software and alarm processing functions.
- Trend log retains a historical record of values for
specified points.
